The speed of the spring when it is released is 3.5 m/s.
The given parameters:
- <em>Mass of the block, m = 2.5 kg</em>
- <em>Spring constant, k = 56 N/m</em>
- <em>Extension of the spring, x = 0.75 m</em>
The speed of the spring when it is released is calculated by applying the principle of conservation of energy as follows;

Thus, the speed of the spring when it is released is 3.5 m/s.

Compounded Quarterly:
A=P\left(1+\frac{r}{n}\right)^{nt}
A=P(1+

nt
Compound interest formula
P=11000\hspace{35px}r=0.057\hspace{35px}t=6\hspace{35px}n=4
P=11000r=0.057t=6n=4
Given values
A=11000\left(1+\frac{0.057}{4}\right)^{4(6)}
A=11000(1+

0.057
)
4(6)
Plug in values
A=11000(1.01425)^{24}
A=11000(1.01425)
24
Simplify
A=15448.0290759
A=15448.0290759

Answer: when the wave encounters something, it can bounce (reflection) or be bent (refraction). In fact, you can "trap" waves by making them bounce back and forth between two or more surfaces. Musical instruments take advantage of this; they produce pitches by trapping sound waves.
Explanation: Any bunch of sound waves will produce some sort of noise. But to be a tone - a sound with a particular pitch - a group of sound waves has to be very regular, all exactly the same distance apart. That's why we can talk about the frequency and wavelength of tones.
Answer:
What make saliva that make your food wet and easy to swallow?
enzyme amylase
Explanation:
The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.
